and has a conspicuous black oblique streak crossing the end of the cell. In Haiti a 
fourth race is found, which is of nearly the same pale tawny colour as C. cillene, but 
the black streak in the primaries of the males extends nearly or quite to the outer 
margin, and the second streak at the apex is but faintly indicated. This Haitian 
insect seems to have no specific name. Both C. delila and C. julia are included in 
Mr. Strecker’s Catalogue of the Butterflies of North America as occurring in Texas.

Though Hiibner in 1816 gave the name Dione to one of his groups of butterflies 
containing species of this genus, the genus itself was not properly defined until 1833, 
when Boisduval and Leconte characterized it under the name of Agraulis, afterwards 
adopted in the ‘Genera of Diurnal Lepidoptera.’ 
The relationship of Agraulis with Colenis as here restricted is very close, the chief 
if not the only important difference being in the middle and hind legs. These, as 
already pointed out by Doubleday, in Agraulis are without either paronychia or pulvillus, 
both being well developed in Colenis. 
The secondary sexual male organs are like those of Colenis, and also very similar to 
those of Heliconius, especially as regards the form of the tegumen, which has an 
internal projecting piece terminating in a point in the middle line, which points out- 
wards and slightly upwards towards the hook of the tegumen. Nothing of this sort is 
to be found in Argynnis and its allies, so far as we have as yet been able to discover. 
The antenne have thirty-nine joints, whereof ten form a gradually thickened terminal 
club. The palpi have the terminal joint short but swollen; the middle joint is long 
and but slightly dilated. The front legs of the male are clothed with fine hair; 
coxa =? femur, tibia = femur; tarsus long (single-jointed *) =} tibia. The claws of 
the middle and hind legs are very straight, and there is neither pulvillus nor paronychia ; 
the outer surface of the tibia is slightly spiny. The primaries have the first subcostal 
branch thrown off before the end of the cell. 
Six species are included in the genus Agraulis, three of which (Ad. vanille, 
A. moneta, and A. juno) have a very wide range in Tropical America. A. glycera is 
restricted to the Andes of Venezuela, Colombia, and Ecuador, A. andicola to Western 
Ecuador, and A. lucina to the valley of the Upper Amazons. A. vanille alone is 
found in the Southern States of North America. 
* In A. lucina the remains of some of the joints seem to be indicated by notches.
